Iv'e heard of a router for a cable modem acting as a "natural Firewall" (?????)
If so, then how does this work?
 
The way I understand it, is that the Router translates the internal IP address to a another address (spoof) and this is what is presented to the Internet Your real IP address is not open for inspection!!
 
I have DSL and it's the modem itself that has a firewall embedded in the firmware.

But I also use Norton's Personal Firewall just to be safe. ;)

Depends on which router you have.

Some routers have many firewall-features, others have not. Every brand and every type has different features and options, so check specifications about a router before you buy it.


Btw. maybe means "natural firewall" that the cable-modem isn't directly attached to your computer, so an atacker doesn't have direct access to your machine when you don't setup portmappings.
